WINDOW-SHADE.

SPECIFICATION forming part of Letters Patent No. 536,507, dated March26, 1895.

Application filed November 22. 1894:. Serial No. 529,588. (No model.)

To all whom it may concern:

Be it known that I, ASA H. BRUMFIELD, a citizen of the United States,and a resident of Anderson, in the county of Madison and State ofIndiana, have invented certain new and useful Improvements inWindow-Shades; and I do declare the following to be a full, clear, andexact description of the invention, such as -will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a front elevation ofinvention applied. Fig. 2 is an enlarged front elevation of inventionpartly in section. Fig. 3 is a plan view of invention. Fig. 4 is adetail of locking piece.

This invention has relation to certain new and useful improvements inmeans for supporting and operating window shades, the object being toprovide a simple and efficient device whereby a shade can be readilyadjusted to cover any desired portion of a window; and the inventionconsists in the novel construction and combination of parts, all ashereinafter described and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates abracket, which is designed to be affixed to the upper central portion ofa window frame or casing as shown in Fig. 1. Said bracket at its upperportion has a horizontal, outward flange a, in which is formed anelongated sloth, which is designed to receive the nose 0 of the lockingpiece 0. Said piece on its inner face has a rib or projection d whichslides in a vertical groove e, in the vertical arm of the bracket A. Thenose 0 of said piece is somewhat pointed and is formed with teeth orserrationsf. On the outer face of said piece 0 is a recessgin whichworks the short arm of an angle lever D pivoted to the bracket at itsangle, and having a perforated bent arm h at its opposite extremity.

E designates the shade whose roll E is hung in bearingsj depending froma transverse bar or rod F. G is the suspension cord the two ends ofwhich are' made fast to the respective end portions of the bar or rod F,

the lower wall of the recess g, and throws the locking piece down out ofengagement with the slot b releasing the cord, the branches of which arebound in said slot by the nose 0. The cord Will then play freely toraise or lower the shade. Bringing the lever back to normal position byan opposite pull on the loop H throws the nose (3 back into the slot 1)and again binds the branches of the cord.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The herein described locking device for window shade cords, saiddevice consisting of a bracket A, having at its upper portion ahorizontal outward flange a, formed with an elongated slot 1), saidbracket also having a vertical grooved arm, a locking piece 0 slidablyseated in the groove of said arm, and

having a tapered toothed nose 0 at its upper end arranged to move intothe said slot 1), and an angular lever bar D pivoted to the said bracketand having a short arm adjacent to the pivot which loosely engages arecess of 2. The means for supporting and operating window shades,comprising the bracket A which is designed to be affixed to the uppercentral portion of a window frame, and which has at its upper portion ahorizontal outward flange a; in which is formed an elongated slot b, thelocking piece 0 having a nose 0 arranged to engage said slot and havingon its inner face a rib or projection (1 arranged to slide in a verticalgroove of said bracket, the angle lever D pivoted to said bracket andhaving its short arm working in a recess in the outer face of the piece0, the transverse bar or rod F, the shade roller-hung in bearingsdepending from said bar or rod, and the suspension cord, the two ends ofwhich are made fast to the respective end portions of said rod or bar,In testimony whereof I atfix my signature the two branches of the cordpassing thence in presence of two witnesses. n to the said bracket anddown throiwhthe V sl ot thereof upon opposite sides of theloek- ASABRUMFIELD 5 ing piece, the loop of the cord passing through iVitnesses:

a perforation in the arm of said angle lever, F. M. REED, substantiallyas specified. SAMUEL P. MOORE.
